Title: Stabilisation of poly-ª-olefines
Inventor: O'NEILL WILLIAM ALEXANDER
IPC: D06P1/651
Filed: 1961-06-30
Abstract: Shaped articles such as fibres, filaments, films, extrusions and mouldings are produced from a polyolefin containing (a) an anionic exchange or basic substance (i.e. a substance which will react with an acid either directly or by replacement of the anion of the exchange substance by the anion of the acid) and (b) an acidic U.V. absorbing agent having a low degree of ionization (i.e. a substance which absorbs light in the region between 3500 and 4000<\>rA and which is less than ten per cent ionized in normal aqueous solution at 20 DEG C.). The polyolefin is preferably derived from ethylene and/or propylene. Substances (a) specified are the oxides, hydroxides and fatty salts of alkaline earth metals and of Mg or Zn (e.g. MgO, Ca(OK)2, the stearates of Zn, Mn and Mg, Zn naphthenate and Mg nonanoate), amphoteric hydroxides such as tin or zinc hydroxide, and hydroxyapatite. Substances (b) specified are hydroxy, substituted benzophenones such as 2, 21-dihydroxy -4- octoxybenzophenone and its nitrated derivative, derivatives of salicylic acid such as methyl 5-octylsalicylate, and unspecified dicarboxylic acids, nitro acids, keto acids, hydroxyaldehydes, diketones and diphenols. The compositions are of improved dyeability, particularly with acid dyestuffs, as is illustrated in the examples using drawn fibres. Specification 935,125 is referred to.

Title: An improved self-emptying ballast tub or skip
IPC: B65D88/58
Filed: 1920-08-13
Abstract: 171,189. Dent, C. H. Aug. 13, 1920. Skips.-A skip, of the type having two sections, provided with inwardly-sloping bottom plates, and hinged together so that they close normally under their own weight, but open automatically under the weight of the contents on the release of a catch, is constructed with the pivot mounted above the top of the container and arranged so that it does not carry the weight of the loaded skip and contents. In the illustrated form, the skip, formed in halves pivoted together at b, is provided with rectangular ends and sloping bottom plates f. It is held in the closed position, when loaded, by arms g pivoted to one section and engaging the other section by means of notches k. Levers o, pivoted on the shaft o<1>, rest on the upper edges of the arms and prevent them from becoming unlatched by vibration. At the dumping-point two cords are pulled to release the latching-mechanism and allow the sections to separate under the weight of the load. The one cord operates the lever p to turn the levers o into a horizontal position. The other cord, which is a.ttached to a lever fixed on the shaft m, raises the forked levers l until the notches k are freed from engagement. The suspension links c relieve the pivot from the weight of the loaded skip and contents.

Abstract: 872,552. Centrifugal pump impellers. SMART, R. E. April 17, 1959 [July 28, 1958], No. 24228/58. Class 110 (1) An impeller for a centrifugal pump comprises an inner shroud or disc 1 formed with integral vanes 4 and a central boss 2 secured on a driving-shaft 3, and an outer shroud or disc 5 having a central aperture 6 traversed by a bridge or spider, the outer shroud or disc 5 being mounted directly on the driving-shaft 3 and abutting against the vanes 4 of the inner shroud or disc 1. The inner and outer discs are keyed to the shaft 3, and the outer disc is held on the shaft by screw means 11. Alternatively or additionally the two discs may be secured against relative rotation by pins, screws or the like. The vanes 4, of curved form, terminate short of the inner disc boss 2 to allow clear space for the passage of fluid, but two vanes run into the boss to form a seating 9 for the bridge or spider of the outer disc 5. The bridge or spider members are streamlined to assist the flow of fluid.

Abstract: 1,099,089. Tapping, machine tool details. O. BILZ. June 1, 1966 [June 5, 1965], No. 24444/66. Heading B3B and B3N. A tap 2, Figs. 2 and 4, is held in a torque limiting chuck 1 having a socket 5, in which a spindle 6 is slidable against a spring 10, spindle 6 being axially, adjustably-fixed to a drive shaft 11, and a ring 15 having a radioactive portion 16 is frictionally held on spindle 6, and co-operates with a screening ring 12 fixed to the end of socket 5. When several taps in a multi-spindle machine are used a Geiger counter 18, Fig. 5, and a Geiger tube 17 pick up signals from any tap 2<SP>1</SP> whose ring 15 is not screened. In operation, portion 16 of ring 15 is inserted into ring 12 to prevent any radiation being picked up by tube 17. The hole is tapped, and spindle 6 does not move axially relative to socket 5. If however the tap does not enter bore 3 of the workpiece 4, or is too blunt to cut properly, spindle 6 moves relative to socket 5, compresses spring 10, and moves ring 15 along spindle 6. When spindle 11 is retracted, ring 15 will move out of screening ring 12, and the Geiger counter will pick up a signal. A warning signal is made, or the machine is switched off, and a new tap is placed in the relevant chuck.

Title: Improvements in indicating means
IPC: G01C17/20
Filed: 1939-08-25
Abstract: 589,801. Indicating-apparatus. FITZGERALD, J. U. P., BREWERTON, A. E., and POWLESLAND, G. T. Aug. 25, 1939, No. 24446. [Class 106 (iv)] The visible reading portion of an indicating instrument is provided with a discontinuous rotary member which is formed in two parts 5a, 5b and constitutes either the figure-bearing element or a masking element having a plurality of spaced viewing apertures 3, each said part being adapted to be angularly displaced periodically in turn with respect to the other part. In the example shown in Fig. 1, the disc 2 carried by the rotating spindle 1 of the instrument has eight viewing apertures 3 and is divided into 10 graduations between the apertures. The two-part elements 5a, 5b carry the figures and are supported on the spindle 1 to rotate relatively thereto. Journalled in these elements are shafts 7a, 7b carrying planet gears 9a, 9b gearing with a toothed wheel 12 carried by the spindle 1. In addition, the spindles carry Maltese crosses 8a, 8b arranged as shown, so that when the spindle 1 is rotated, a slot in the cross engages the pin 11 on a fixed disc 10 and the corresponding shaft 7a or 7b is turned relatively to the spindle closing the gap between parts 5a, 5b at one side and then again at the other alternately. The graduations seen through the openings 3 visible under the fixed shield 13 are as shown, 150, 160, 170, and before the disc 2 emerges from under the shield 13, the graduation 180 has moved under the next opening, by the closing of the upper gap in the drawing in the manner described above. Practical embodiments are described, wherein the discs and wheels shown spaced along the length of the spindle 1 in Fig. 1 are brought close together as they would be in practice. The two parts may overlap instead of having a sector gap, and in one form the parts are formed of two toothed gears overlying one another, the top one having cut-away portions and both having lugs and small gaps in the teeth which co-operate with the driving pinion to give the relative movement. The figure bearing and mask parts may be of drum, conical or other form. Specifications 142,894, [Class 106 (iv)], 419,002, 433,322 and 460,632 are referred to.

Abstract: 644,606. Velocity-modulated tubes. STANDARD TELEPHONES & CABLES, Ltd. Sept. 8, 1947, No. 24651. Convention date, April 12, 1946. [Class 39 (i)] In a velocity-modulation tube, an annular beam of electrons is projected successively across a modulation gap 4 in a cavity resonator 3, a drift-tube 5 and a pick-up gap 7 in cavity resonator 6. The beam has a cross-over in each gap. It is then reflected by an electrode 8 back through the resonator 6 to reinforce the oscillations therein. The reflector electrode and the drift-tube 5 are so shaped that the forward and reflected electron beam paths are separated except at their common cross-over. The reflected beam is collected after emerging again from the second resonator 6 by an annular electrode 10 encircling the drift-space. Specification 580,081 is referred to.
